例句

As I mentioned, paravirtualization requires the guest operating systems to be modified for the hypervisor, which is a disadvantage.

正如前面介紹的一樣，超虛擬化技術需要為hypervisor修改客戶操作系統(tǒng)，這是它的一個缺點。

As shown in Figure 5, the guest operating system includes a thin layer of Lguest code (by definition, paravirtualization).

如圖5所示，來賓操作系統(tǒng)包含一個Lguest代碼瘦層（根據(jù)定義，就是準虛擬化）。

KVM leverages the core features of the Linux kernel, including paravirtualization interfaces contributed by IBM engineers.

KVM充分利用了Linux內(nèi)核的核心特性，包括由IBM工程師貢獻的泛虛擬化（paravirtualizaiton）接口。

This article touched on a two virtualization mechanisms: full virtualization and paravirtualization.

這篇文章談論兩個虛擬化機制：完全虛擬化和半虛擬化。

OKL4 implements paravirtualization, which means that operating systems must be instrumented to run on the microvisor.

OKL4實現(xiàn)了半虛擬化，意味著操作系統(tǒng)必須能在microvisor上運行。

The Lguest hypervisor took this a step further, and with the constraints of paravirtualization, minimized the solution even further.

Lguest進一步改進了這種方法，并且通過受限制的準虛擬化進一步簡化了該解決方案。

In the paravirtualization scheme, the guest and the hypervisor can work cooperatively to make this emulation efficient.

在半虛擬化模式中，來賓操作系統(tǒng)和hypervisor能夠共同合作，讓模擬更加高效。

This article begins with an introduction to paravirtualization and emulated devices, and then explores the details of virtio.

本文在開篇時介紹半虛擬化和模擬設備，然后探索virtio的細節(jié)。

Xen is a free open source solution for operating system-level paravirtualization from XenSource.

Xen是一個來自于XenSource的操作系統(tǒng)級超虛擬化的免費開源解決方案。

You can exercise this paravirtualization infrastructure today in the Linux kernel.

現(xiàn)在，您可以在Linux內(nèi)核中實踐這個半虛擬化基礎架構。

In sum, Virtio delivers most of the performance benefits of paravirtualization.

總之，使用Virtio可獲得半虛擬化的最佳性能收益。

The system relies on paravirtualization, so that guest operating systems are aware that they are virtualized.

此系統(tǒng)依賴半虛擬化，以便來賓操作系統(tǒng)意識到它們已被虛擬化。

Paravirtualization is a technique in which a software interface that is similar but not identical to the underlying hardware is presented.

泛虛擬化是這樣一種技術，軟件接口以與底層硬件相似但并不完全一致的方式得以呈現(xiàn)。

The right side of Figure 1 shows the paravirtualization case.

圖1的右邊是半虛擬化示例。

User-mode Linux is another paravirtualization solution that is open source.

User-modeLinux是另外一個超虛擬化解決方案，也是開源的。
